Test evaluation
Using large ear rabbit as research object, left femoral artery is sufficiently exposed after anesthesia, then uses scalpel by every group 3
War injury bleeding is simulated in the notch of the standardized 0.5cm depth of artery surface.After giving free rein to bloodletting 3s, corresponding timely hemostatic yarn is used
Cloth and tourniquet bandage pressing carry out hemostasis intervention.The bleeding stopping period and the highest temperature in hemostasis for recording every large ear rabbit
Degree, is respectively averaged.As a result referring to table 1.
Table 1
As can be seen from Table 1, comparative example 1 is related to that the situation of potassium chloride is not added, causes its exothermic effects more obvious；Than
Zeolite and the comparable situation of kaolin average grain diameter are related separately to compared with example 2-3, the former is Nano Particle, and surface area is caused to increase
Greatly, increase with contacting blood area, bleeding stopping period is greatly decreased, also results in zeolite exothermic effects and obviously increase；The latter is
Hundred micron-level particle sizes, bleeding stopping period are significantly increased.Comparative example 4-5 relates separately to zeolite and kaolin ratio is 1:1's and 2.5:1
Situation, since zeolite ratio increases, bleeding stopping period increases, but exothermic effects are also significantly increased simultaneously.It can be seen that exothermic effects
It is closely related with the partial size and ratio of zeolite.Comparative example 6-7 relates separately to the situation that very few potassium chloride and excessive potassium chloride is added,
The former inhibits exothermic effects unobvious, and the latter will lead to skin tingle, and being in a tumult strongly occurs in test large ear rabbit.
And the timely hemostatic gauze and tourniquet bandage of 1-3 of the embodiment of the present invention then provides faster haemostatic effect, simultaneously
Inhibit the exothermic effects of zeolite.It is believed by the inventors that the zeolite and kaolin composition of this and special ratios of the present invention and partial size
And the potassium chloride of special ratios is closely related.The combination of features described above is to present invention offers unexpected technical effects.
Medical orderly's knapsack of the invention can satisfy the demand that bleeding is controlled under harsh combat conditions as a result,.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
